1 Zaïre 5 Years of J.D. Mobutu's Presidency, Gold Proof Issue

Issued to mark five years of Mobutu Sese Seko's rule, this proof was struck before the sweeping Authenticité campaign that would, within two years, rename the country Zaïre, rename the currency, and require citizens to abandon European names entirely. The coin's attribution to the Banque Nationale du Congo rather than a successor institution dates it precisely to that transitional window — Mobutu was consolidating power but had not yet rewritten the national identity wholesale.

The .900 gold proof series of this type was produced in extremely limited quantities for diplomatic gifting and elite collectors. Few entered open commerce at issue.
